Cullen left the Templar Order because he didn't want to massacre mages in the name of religion. Whether or not he's an addict won't change that part of him.
Blackmail Josie with *what* exactly? I mean sure you can invent some power fantasy here but who will be your enable? Her friend Leliana? You're kidding yourself.
The IB is quite clearly not pro-massacre. He turned himself over for reeducation because he couldn't handle the violence in Seheron.
You could certainly fantasize about killing Sera but she'd oppose you - you're everything she hates about nobility.
Leliana is the BIGGEST reformer of the Chantry. She wants to abolish the Circles and include the elves into the priesthood. A ruthless Leliana would be your absolute greatest nemesis. Your very agenda is an offence to everything she holds dear.
It goes on. None of these characters would support hard line religious bigotry. I suppose you could lament the lack of "Torture is actually great!!!!" situations from ME but IMO that's not really evil.
Does Cullen become more anti Mage again if made to take Lyrium? Mind you I've never done it, I can only go on what I've heard. Either way. The Inquisition can be in the position of controlling his lyrium supply. He isn't going anywhere.
Didn't Josie have a a gang of assassins after her AND is stuggling to make ends meet and take care of her decaying noble house. No power fantasy is needed to take advantage of her.
IB will do as he's told. Before the Chargers are killed because he has a job to do. So no he won't be a problem. If you keep the Chargers alive, he'll probably be an issue then. In which case he can leave. If the Chargers are killed, he's still apart of the Qun and will not leave until Cory is gone.
You mean the same Leliana you can harden and will be planning Exalted marches before she's even made Divine. Hardly.
But keep on trying to claim that all the characters in this game are morally good people and how the game would never work with a ethically questional IQ. And mind you I'm not arguing the religious percecution scenario completely, but the very idea that having an IQ that is anything other than a good and noble person would never work because, as you claim, the game could never work like that. My opinion is that the game could work if we were given the options.
**As for Cass. I don't see her as a major reformer. I can easily see how her reforms will eventually end up with everything going back to business as usual. And I can see her approving of favorable Andrastian options that are more pragmatic. Whether it's percecuting another group, depending on the choice, would be debatable. (i.e Conscripting Mages)
